The difference between waterproof wall and firewall

The waterproof wall is used to prevent the information from leaking from the internal network, and the firewall is between the external network and the internal network to prevent the information from leaking from the internal network to the external network!

In other words, I think the waterproof wall in Li Shan is good and fully functional.

File security needs to be guaranteed from the following aspects:

Strong confidentiality: prevent unauthorized users from obtaining file contents, and prevent confidential files from being leaked due to the loss of storage devices.

Tamper-proof: Prevent unauthorized users from tampering with document contents.

Availability: Ensure that authorized users can use confidential data, including employees in the company network, employees on business trips, customers and partners.

Leak prevention: prevent authorized users from sending documents or document contents to others through copying, mobile storage, network transmission, printing, etc. After obtaining the file, it leads to the spread of confidential data.

Anti-recovery: prevent data carriers such as hard disks from being turned into security nightmares by people with ulterior motives using various recovery tools when they are out of the sight of managers for maintenance.

The direct purpose of document security is to ensure the security of documents, to ensure that confidential data can only be used in a safe environment, and to control the use of confidential data even outside a specific network environment. But don't affect the processing efficiency of the document itself too much, and change the use process of the document.

Li Shan waterproof wall information security management system (data leakage prevention system) has dual management objects:

1, the object of management is the computer itself first. For example, manage the IT assets of computers, manage the ports and media of computers, and manage the use of computer programs.

2. The managed objects also need to be documents with various security levels existing on the computer. These documents are the real source of wealth. One of the goals of management is not to prevent leaks.

Around the world, various countries have introduced various laws to control information auditing, among which SOX Act in the United States and cryptogram in Japan are the representatives. The China Municipal Government has formulated a series of laws and regulations, such as Basic Standards for Enterprise Internal Control, Grade Protection and Grade Protection, to evaluate and manage the information security of different types of organizations, and the comprehensive information security popularization work is being vigorously promoted in China.
